WINDOW.

SPECIFICATION forming part of Letters Patent No. 660,235, dated October23, 1900.

Application filed December 7, 1899. Serial No. 739,@78. (No model.)

Tn @ZZ whom it may concern,.-

Beit known that l, GEORGE WORTH, a citizen ofthe United States,residin gat New York, (Brooklym) in the county ofKings and State of New York,have invented certain new and useful Improvements in Windows, of whichthe following is a full and complete specification, such as will enablethose skilled in the art to which it appertains to make and use thesame.

This invention relates to revolving windowsashes, and one object thereofis to provide a window frame and sash therefor which shall be' capableof easy manipulation, which will permit adjustment of the' sash tobalance lthe same accurately, which sash shall be held closely incontact with the stop-,beads to make an approximately air-tightconnection and prevent rattling, and in which the sash is supported bythe sash cords or chains in such manner that the strain of thesash-weights upon the sash through the medium of the sashcords is alwaysapplied vertically, whereby the sash may be positively and evenly raisedand lowered.

With these and other objects in View my invention consists in theconstruction and arrangement of parts hereinafter set forth.

In the accompanying drawings,forming part of this specification, inwhich like reference characters denote like parts in the several views,Figure 1 is a central sectional elevation of a window constructedaccording to my invention; Fig. 2, a vertical section of a portion ofsaid window-frameand a vertical elevation of a portion of said sashconnected therewith and partly cut away to show the internalconstruction, the whole being on an enlarged scale; Fig. 3, an edge viewof a portion of said sash and a member thereof, being in alteredposition and upon `au enlarged scale; Fig. 4, an edge view of a portionof said sash upon an enlarged scale; Fig. 5, a vertical section of aportion of said sash, several of the parts being shown in full lines;and Fig. 6, a transverse section of the side of the sash and asupplemental member connected therewith.

In the practice of my invention I provide a window-frame 7, the verticalportions 8 of which are provided with the usual stop-beads 9, andbetween which slidably operate the sashes, respectively designated bythe general reference characters 10 and 11, provided with window panesl2. The construction and mounting of-the sashes l0 and 11 are the same,and for simplicity I will refer to but one th`ereof, 10, in thefollowing description, the reference characters referring to both.

Each of the sides Vl2 of the sash 10 is chambered at 13, and a plate 14is secured to the yside edgeof the sash across the orifice of saidchamber by fastening devices 15, and t-he central portion of said plateis struck up at 16 and provided with a longitudinal slot 17. A plate 18tits the central portion 16 of the plate 14 and is shorterthan the sameand capable of adjustment longitudinally thereof, being connected withthe slot 17 therein by bolts and nuts 19. The sash 10 is provided lateach side with a coextensive supplemental member consisting of a strip2O of suitable material fitted thereto by a plurally-curved surfacewhich matches a similar edge surface of the sash side 12, as shown at 21in Fig. 6. The strip 2O ts between two of the stop-beads 9 and istransversely chambered at 22 and provided with a casing 23, which is setthereinto and secured thereto at 24. The casing 23 is annularly angedupon its inner edge at 25, and the plate 18 is provided with anoutwardly-directed collar 26, which projects into the chamber 22 andupon which the sash 10 hangs, the flanges 25 operating as bearingstherefor. The sash 10 is thus free to swing upon the collars 26 at eachside thereof, and as the plates 18 can lbe adjusted relative to theplates 13 by means of the slots 17 and fastening devices 16 the sash mayalways be maintained in equilibrium. A stud 27 is secured in each of thecollars 26, and a coiled spring 28 is imposed thereon and upon thecollar 26, operating within the chamber 22 and against the flange 25 anda detachable cap 28, passed upon the stud 27 and secured thereon by apin 29. The strips 20 exactly fill the spaces between the stop-beads 9,between which latter they operate, and the sash may thus entirely swingfree thereof.

Above the chamber 22 the strip 20- is chambered at 30, communicatingwith a continuous chamber 3l, extending to the adjacent end of saidstrip. A plate 32 is set into the IOO strip 2O directly beneath thechamber 30 and secured in place by a fastening device 33. The plate isprovided with a hooked upper end 34, which is directed into the chamber30. A link member (denoted bythe general index character is providedwith a lower transverse end 36 which iits the hooked end 34 of the plate32 and is free to turn therein, aud with parallel vertical sides 37 andacu rved upper transverse end 38, provided with a central slot 39. Thesides 37 of the link 35 are provided with cheeks 40, in which arepivoted side bearings 4l of a pivoted plate 42, provided at its upperend with an inwardlydirected hook 43, which operates within the chamber30 and between the sides of the link member 35.

The sash-supporting cord or chain 44 is passed through the slot 39 inthe end 3S and engaged with the hook 43, and the other end thereofpasses upwardly, as shown in Fig. 1, and about a pulley 45, set into theside 7 of the window-frame, and thence passes downwardly in the usualchamber in the frame, (not shown,) where it is connected with thesash-weight.

A screw-stud 46 is sunk into the strip 20 within the lower portion ofthe chamber 30, and loosely mounted thereon is a frameshaped device 47,secured in position uponY said stud by a washer 48 and nut 49, and t-heframe-shaped portion device 47 is provided at the upper end with heads5l, in which are journaled the end bearings 52 of a roller 53, which isprovided with a central peripheral beveled rim 54. The heads 5l areconnected by a circular crossdiead 55, which carriesa central stud 56,which operates within the chamber 30 and within an opening 57 in thestrip 20. Ahelical spring 58 is imposed upon the stud 56 and normallyprojects the frameshaped device 47 or the upper end thereof, said springbearing upon the cross-head 55 and the strip 20 adjacent the opening 57.rlhe strips 2O at either side of the sash are also chambered at 59 belowthe chambers 22, and the frame-shaped device 47, roller 53, rim 54,cross-head 55, stud 56, spring 5S, and connected parts are duplicated insaid chamber 59. The rims 54 of the rollers 53 bear operatively againstthe sides S of the window-frame 7 between the stop-beads 9, beingpressed thereagainst by the springs 58, and thus serve as antirattlersfor the sash, causing the same to occupy a rigid position in thewindowframe. In operating said rims form grooves in the frame sides 8,in which they operate.

The sash hangs upon the sash-chain 44, which is connected with thepivoted plate 42, which is pivoted to the link member 35, which in turnis pivoted to the plate 32, and hence the sash-chains always pullvertically upon the sash, and the sashes and strip members 2O ridevertically between the stop-beads 9. The sashes may also be swung in avertical plane, as shown in Fig. l, upon the collars 26, which bear uponthe flanges 25, and by means Y of the relatively-adjustable plates i4and i8 the sashes may always be maintained upon a true pivotal center.

I have shown but one side of the sashes as provided with myim provedconst ruciion; but. it is understood that the latter is duplicated uponthe other side and that both sashes 1.0 and ll are identical in regardto the improved construction described.

I do not limit myself tothe specific construction and arrangement ofparts herein specified, but reserve the right to vary the same withinthe scope of my invention.

Having fully described my invention, I claim as new and desire to secureby Letters Patentl. The herein-described windowsash which operates inconnection with a window-frame provided with stop-beads, comprising amain sash portion provided at the sides with chambers in which are sunkslotted plates; and su pplemental sash members, comprising strips whichfit between said stop-beads and are chambered to receivebearing-casings, other plates adjustably connected with said firstnamedplates and provided with bearing devices which operate in connectionwith the bearing-casings in said supplemental strips, said bearingdevices being provided with spring-projected extensions which operatewithin said chambers in said strips, said strips being further chamberedand provided therein with pivotally-mounted devices with which the sashcords or chains are pivot-ally connected and with loosely-mountedtensional devices which bear upon the window-frame, substantially asshown and described.
